‘The Global Communion’ examines how overseas expansion raised challenges to central authority under the supremacy of the King of England. Even in the seventeenth century, the Scottish and American bishoprics' loyalty was in doubt. The American Revolution led to an independent Episcopal Church. The Canadian Church remained closer, but was a minority denomination in Canada. In India and Australasia, dioceses and mission agencies' authority came into conflict, with synodical government eventually replacing English leadership. In Africa, missionary encounters revealed the need to reshape Anglicanism for alternative contexts. The global spread of Anglicanism led to the development of the Anglican Communion, which was born out of a sense of pan-Anglicanism.
